Swiss officials are debating whether fugitive U.S. whistleblower Edward Snowden could receive asylum to testify in state investigations into foreign espionage against Switzerland.

The Swiss newspaper "Le Matin Dimanche" reported September 7 that the federal Prosecutor-General's Office has sought legal opinions regarding whether Snowden would be immune from U.S. extradition demands.

The paper says the legal opinions conclude Snowden could be given asylum if "higher state obligations" did not take priority.
